Title: Method and apparatus for reducing residual ammonia content in fabric processed with liquid ammonia
Inventor: LAWRENCE JACKSON
IPC: D06M11/61
Filed: 1976-09-21
Granted: 1980-04-15
Abstract: AMMONIA PROCESSING OF FABRICS Abstract of the Disclosure The disclosure relates to equipment and techniques for the removal from fabrics of excess residual ammonia, remaining in the fabric after liquid ammonia processing.  The process in-volves contacting the opposed surfaces of the fabric with a thin film of water, followed by removal of the water from the fabric. The amount of water which contacts the fabric is insufficient to wet the fabric, so that it does not require a subsequent dry-ing step, but is sufficient to release most of the residual ammonia, causing the ammonia to be extracted from the fabric. To advantage, the thin film of water is achieved by condensation of steam on chilled rollers.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved sealing mechanism for closing the bottom opening of a toilet bowl and adapted to be moved between open and closed posi-tions with a minimum of human effort. The mechanism includes a movable blade and an elastic seal in the form of a curtain that functions to wipe foreign material from the blade when the latter is moved between open and closed posi-tions, the curtain also functioning to provide a seal when the blade is in its closed position. The blade is supported so that when in its closed position it will always align itself with respect to the curtain to maintain an optimum seal. The blade is pivotally supported on an arm of a vertically disposed crank which is spring-actuated to an upper position and which can be depressed and pivoted for moving the blade between its closed and open positions.

Abstract: TOY CASH REGISTER CONSTRUCTION     ABSTRACT OF THE DISCLOSURE           A toy cash register including, in one embodiment, a plastic case having a drawer compartment at the bottom and main mechanism and target display compartments above the drawer compartment.  A horizontal metal frame plate defines the top of the drawer compartment and the bottom of the main mechanism compartment.  The targets and their operating and release mechanism are supported on the top of the metal frame plate by a plastic target frame carried thereby.  A bell and clapper are supported by the target frame below the metal plate and above a cash drawer slidable in the bottom compartment.          The means for opening the drawer consists of a wire spring formed as a simple loop of generally circular form which reacts outwardly against the drawer and inwardly against the case.  In one embodiment the spring is carried by the case, and in another embodiment by the drawer.  The drawer is guided by a portion of its operating mechanism.

Abstract: ABSTRACT:          In third-generation transversal tomography scanners, where the  total body slice to be examined is irradiated by a flat, fan-shaped radiation beam, the probability that a detector which measures part of the radiation in the radiation beam becomes defective is very high. This failure causes artefacts in the reconstruction of the absorption distribution of the slice of the body, said artefacts  having an adverse  effect on the evaluation of the image by the radiologist. The invention ensures that a defective detector is identified (for example, by com-parison of the measuring values supplied by each detector with the  measuring values of adjacent detectors), the measuring value  of a detector which has been identified as being defective being replaced by a correction value which can  be formed by  interpolation of measuring values obtained  along  neighbouring paths.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to thyristors of the type having an auxiliary thyristor for amplifying the control current of the thyristor.  This type of thyristor has a control electrode and an auxiliary emitter electrode.  In known constrictions, operation of the auxiliary electrode and the control electrode is effected by inter-related circuitry.  In the disclosed thyristor the control electrode and auxiliary emitter electrode are each provided with a separate control line connected to terminals in the thyristor housing for the connection of external leads.  Thus, the control and auxiliary emitter elect-rodes can be controlled separately and, in particular, the turn-off time can be reduced by applying a negative voltage from an external source to the auxiliary emitter.  This arrangement avoids the problem of providing circuitry in the thyristor to prevent control current from flowing into the auxiliary emitter.

Abstract: Case No. 4411.21 COOLING FAN CONTROL            Abstract An electromagnetically controlled clutch is used to engage and disengage the cooling fan of a water cooled motor vehicle engine.  The clutch and fan assembly in the form of an adapter kit may be attached to the existing fan mountings normally located on the water pump pulley assembly.  The adapter kit includes an extender cylinder which bolts to the existing fan mountings.  Bearings are provided inside this cylinder for rotationally free mounting a fan mounting hub supported on a shaft, which is free to rotate within the extender hub.  An annular armature is spaced from the pulley assembly and supported around the hub by leaf springs, attached at one end to the hub and at the other end through rigid extender arms to the armature.  A clutch face is provided on the water pump pulley and an electromagnet coil is fixedly mounted to the engine block in a recess in the pulley for attracting the armature under the control of a temperature operated switch, which energizes the coil when the temperature of the engine coolant exceeds a preestablished value to draw the armature into contact with a clutch face on the pulley assembly to rotate the fan.

Abstract: Abstract A modular lightweight structural panel is made of a lightweight expanded plastic filler reinforced by wire lattice structures.  A number of long, narrow filler elements are inter-leaved with a number of substantially flat lattice structures to form a laminated panel subassembly with corresponding surfaces of the filler elements collectively forming substantially planar surfaces of the panel core.  The subassembly is laterally com-pressed, in a direction perpendicular to the planes of lamina-tions, to thereby force each of the lattice structures to be pressed into and partially embedded in mutually contiguous surfaces of adjacent ones of the filler elements.  While in such compressed condition, a number of cross-members are fixed to side portions of the several lattice structures that protrude beyond the panel surfaces to thereby hold the assembly in its pressed condition with the lattice structures embedded in the filler elements and the surfaces of adjacent filler elements in close physical contact with one another.  The completed panel assembly is thereafter coated with a suitable mixture of con-crete, plaster, or the like.
